Specification forming part of Letters Patent No. 115,308, dated May 30, 18,71.

To all whom it may concern:

port, in the county of Monmouth and State of New Jersey, have invented a new and Im proved Apparatus for Soldering Caps to Tin Gans; and I do hereby declare that the following is a full, clear, :and exact description thereof, which will enable others skilled in theartto make and use the saine,'reference "being hadto the accompanying drawing form- .i ling part of this specification, in which- Figure 1 represents a vertical longitudinal section of "my improved apparatus for soldering caps to cans, the line x w, Fig. 2, indicating the plane of section. Fig. 2 is a side elevationfof the saine. Fig. 3 is a longitudinal j `section on'a'n enlarged scale of the solder-pistol. Fig. 4 is an end view of the same.

Similar `letters of reference `indicate corresponding parts.`

Myinvention consists of certain improvements in means for soldering cans, which will be rstdescribedlin connection with all that is necessary to a full understanding thereof, and thenclearly pointed out in the claim.

Ain the drawingrepresents a stove or furnace of .suitable size and shaped provided `with a grate, a, and connected withastovepipe, Nb, as indicated, so that it may contain fuel in a state of combustion. Into openings in the sides of the stove A are tted blocks B B, of copper or other metal, which 'become e heatedby the fire within the stove. Each blockB serves `to hold a soldering-iron, G,

whichis, by astrap, c, or equivalent fastening, secured tothe outer face of the block, as

indicated jinEigs. l and 2. The lower point or end of `theisoldering-iron is to work on the can, and must, therefore,project from the side of the stove, as shown in Fig. 1. The connection of the solderingiron with the block is sufficient to heat the point or end of the iron to the desired`degree. rlhe stove is placed upon a suitable tableorvframe, DL e The same serves to support a turn-table, E, infront of l each soldering-iron C andblock B. Each turntableis a disk or plate of such size that `it will properly support the can to be soldered, hav*- `Be it known that I, J AcoB GULDEN, of `Keytical shaft, c, which rests and is swiveled in a step, j', that is pivoted to a lever, F. This lever is, at g, pivoted to a pendant or portion of thefraine D,andis, at its front end, conwhereby it can be swung up or down to raise or lower the turntable. A spring, c, is connected with the lever F, to keep it and the table E elevated. The shafte passes through stationaryperforated earsjj, which retain it .in a vertical position, the pivoted step f adjusting itself, as to its angle with the lever, to every new position of the saine. To the shaft c is secured a cord or chain, k, which is weighted at one end, as at Z, and can be pulled by hand'or treadle at the other end. By pulling said cord the shaft will be revolved with the turn-table, and the weight raised, and by in the opposite direction. e

The can to be soldered is placed upon the turn-table, andthe cap m held down upon it bya tripod, n, which is swiveled in an arm, o, that projects from an upright vertically-adjustable shaft, G. A spring, 10, serves to draw the tripod down upon the cap, a'ud to thereby retain the latter on the can. The swiveled shank of the tripod being in line with the shaft e, it follows that the cap will revolve with the the 4turn-table. rEhe point or end of the soldering-iron reaches the can where the solder to be applied for securing the cap. When solder is held against the face of the heated iron G and the can revolved, an annular layer of solder will be applied to the can so as'to secure the" cap to the saine. The solder to be used is put up in sticks or bars of suitable shape. Each such bar, H, to be used is placed into a tube or hollow case, I, which, on a projecting ear, q, carries a pivoted lever, J. To the iront end of the lever J is pivoted a pawl, r, which, with its sharpened or biting lower end, passes through a slot in the tube or case I and reaches the bar H of solder. A spring, s, draws the point of pawl back toward the ear q whenever the handle of the lever is pressed down. Aspring', t, stronger than s, is placed under the handle end of the lever and raises it, so as to push turn-table is affixed to the upper end of a vernected with a treadle, hor equivalent device,`

then letting go the cord they will be revolved can Whenever the same is revolved on and by When the lever J is pressed down the pawl o' is drawn back loose, and takes a fresh hold On the bar, pushing the same forward the desired length by the power of the spring t when released.

The attendant has thus only to depress the lever J and hold the end of solder projecting from the case I against the iron C, when the projecting portion of the solder will nielt down to be used on one can. For every subsequent can the lever is again depressed to feed the bar H the requisite distance ahead.

This solder-feeding implement I call the solder-pistol. It is very convenient and economizes solder, as no more but what is absolutely required for each can will be let out.

Having thus described my invention, I claim' as new and desire to secure by Letters Patentl. rEhe arrangement of a tool-holder, B, in the side of furnace A, resting upon the firegrate a, and abutting laterally upon the fire, for the purpose of firmly holding the tool, easily transmitting heat `thereto, and readily retaining said heat at the proper temperature.

2. The metallic block B, having a recess to receive the tool and hold it rmly on three sides, combined with a transverse' strap and fastening-screw to form a holder for solderingtools, which will admit of their ready attachment and detachment, as described. y

3. The case I, pawl r, and spring-lever J, combined and constructed as and for the purpose specified.
